Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    The universe is not rough-hewn, but perfect in its details. Nature will bear the closest inspection; she invites us to lay our eye level with the smallest leaf, and take an insect view of its plain. She has no interstices; every part is full of life.
    Henry David Thoreau (1817–1862)

    I saw the spiders marching through the air,
    Swimming from tree to tree that mildewed day
    In latter August when the hay
    Came creaking to the barn.
    Robert Lowell (1917–1977)
